Xuan Gong commented on YARN-297:
--------------------------------
So, those java files use small primes,31, and seed value as 1 to generate the
hash value:
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/ApplicationAttemptId.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/ApplicationId.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/ContainerId.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/NodeId.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/Priority.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/Resource.java
./hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/ResourceRequest.java
